System and method for simultaneous drying of heating furnace and sulfurization of hydrogenation catalyst

Abstract

The invention discloses a system and method for simultaneous drying of a heating furnace and sulfurization of a hydrogenation catalyst. Drying of the heating furnace is synchronized with sulfurizationof the hydrogenation catalyst; drying of the heating furnace is carried out by heating the heating furnace by combustion of coke oven gas introduced into the heating furnace; and heating during sulfurization of the hydrogenation catalyst is realized by the steps that a heating medium in a medium pipeline is heated along when the heating furnace is heated, and then the heating medium with a high temperature is obtained for heating in a form of heat exchange. According to the system and method provided by the invention, the start-up time can be reduced and production efficiency can be improvedunder the condition of meeting requirements of oven drying of the heating furnace and sulfurization of the hydrogenation catalyst. In addition, the usage amount of coke oven gas is saved, and the function of reducing production cost is achieved. Moreover, sulfurization of the hydrogenation catalyst is synchronized with the oven drying of the heating furnace, so that the time for drying the hydrogenation catalyst and removing water adsorbed by the hydrogenation catalyst can be prolonged, and thus the sulfurization effect of the hydrogenation catalyst is better.

Description

technical field

[0001] The invention belongs to the technical field related to methanol production from coke oven gas, and in particular relates to a system and a method for vulcanizing a hydrogenation catalyst synchronously in a heating furnace. Background technique

[0002] During the initial start-up process of the coke oven gas-to-methanol device, the heating furnace needs to be baked first to remove the moisture contained in the refractory bricks and refractory castables inside the heating furnace, so as to prevent the occurrence of The rapid evaporation of water caused by heating causes damage to the lining of the furnace body, thus ensuring the normal and stable operation of the furnace body under high temperature operation. Moreover, a hydrogenation catalyst needs to be used in the process of producing methanol from coke oven gas to convert organic sulfur in coke oven gas into hydrogen sulfide, so as to achieve the purpose of removing organic sulfur.
